Physiologically active substance collecting device and biological information acquisition method

Abstract

A physiologically active substance collecting device, includes: a collecting section brought into contact with a body surface of a living organism to acquire a physiologically active substance from the body surface; and a liquid sending means for sending a solvent to the collecting section, the collecting section having an aperture at which the solvent flown by being sent from the liquid sending means contacts the body surface.

The application is claimed as follows: 
     
       1. A physiologically active substance collecting device, comprising:
 a collecting section brought into contact with a body surface of a living organism to acquire a physiologically active substance from the body surface; 
 one or more channels for sending a solvent to the collecting section, the collecting section having an aperture wherein the solvent flows through the one or more channels to contact the body surface; 
 an air sending unit that sends air to the collecting section to selectively introduce the solvent and air into the collecting section 
 a lead-out section that drains the solvent that has contacted the body surface at the aperture; 
 an absorber that is sent to the lead-out section to absorb and hold the solvent, wherein the absorber that absorbs and holds the solvent is sent to the lead-out section by rotating a core and reeling out the absorber wound around the core; and 
 a drying unit for evaporating and removing the solvent from the absorber absorbing and holding the solvent. 
 
     
     
       2. The physiologically active substance collecting device according to  claim 1 ,
 wherein the collecting section includes a collection substrate that includes a first channel that provides a flow path for the solvent, a solvent inlet for the first channel, a solvent outlet for the first channel, and the aperture positioned between the inlet and the outlet of the first channel. 
 
     
     
       3. The physiologically active substance collecting device according to  claim 2 , wherein the collection substrate is replaceable from the collecting section. 
     
     
       4. The physiologically active substance collecting device according to  claim 2 , wherein the collecting section includes an anchor substrate that includes a second channel that provides a flow path for the solvent sent from a solvent tank and a third channel that provides a flow path for the solvent sent to a lead-out section that drains the solvent that has contacted the body surface. 
     
     
       5. The physiologically active substance collecting device according to  claim 4 , wherein the anchor substrate is anchored to the collecting section.
